inflation

Introduction

Inflation, the continuous rise in prices or the fall in the value of money, is a critical economic phenomenon that affects various aspects of the economy, including financial markets, asset returns, and the overall economic well-being of individuals. Understanding the causes, effects, and implications of inflation is essential for policymakers, economists, and financial analysts.

Key Insights

Inflation and Financial Sector Performance:
- High inflation negatively impacts banking sector development and equity market activity, with a nonlinear relationship where the marginal impact diminishes as inflation rises. Economies with inflation rates exceeding 15% experience a significant drop in financial sector performance.
Inflation and Asset Returns:
- Inflation affects asset pricing differently based on its underlying causes. "Good" inflation linked to demand shocks and "bad" inflation linked to cost-push shocks have distinct implications for financial markets.
Monetary Phenomenon:
- There is a strong long-term relationship between money supply growth and inflation. Historical data shows that major changes in inflation rates are closely tied to changes in the money supply .
Global Nature of Inflation:
- Inflation in industrialized countries is largely a global phenomenon, with a common factor accounting for a significant portion of inflation variance across OECD countries. National inflation rates tend to revert to global inflation trends.
Inflation Expectations:
- Individuals' expectations about future inflation are heavily influenced by their lifetime experiences with inflation. Younger individuals adjust their expectations more strongly to recent inflation experiences compared to older individuals.
Inflation and Variance:
- Empirical evidence shows a positive association between the average rate of inflation and the variance of inflation. This relationship can be explained by the incentives facing policymakers in a discretionary equilibrium.
Political and Social Factors:
- Inflation can also be driven by social and political factors, not just economic or monetary ones. These factors can interact with economic variables to influence inflation rates.

Conclusion

Inflation is a multifaceted phenomenon influenced by monetary policy, global economic trends, individual expectations, and political and social factors. High inflation can adversely affect financial sector performance and asset returns, while the relationship between money supply and inflation remains robust over the long term. Understanding these dynamics is crucial for effective economic policy and financial market analysis.

Sources and full results

The impact of inflation on financial sector performance

Inflation negatively impacts banking sector development and equity market activity, with a threshold at 15% inflation where performance drops significantly.

Inflation and Asset Returns

"Good" inflation is linked to demand shocks, while "bad" inflation is driven by cost-push shocks, impacting asset pricing and inflation risk premia in a rising inflation world.

Inflation: A Survey

Inflation is a major social problem, as it affects the well-being of everyone due to its pervasive role in modern economies.

The Demand for and Supply of Inflation

Inflation is a monetary phenomenon, and its demand and supply are influenced by the growth of the money supply.

The Long-Run Link between Money Growth and Inflation

The long-run relationship between money growth and inflation in the United States remains strong and important, with the trend component in CPI inflation being entirely due to monetary base growth.

Inflation in open economies

Inflation rates in open economies are linked to trade openness due to imperfect competition and nominal price rigidity in the non-traded sector, rather than large-country terms of trade effects.

Global Inflation

Inflation in industrialized countries is largely a global phenomenon, with a robust error correction mechanism bringing national rates back to global inflation, improving inflation forecasting.

Learning from Inflation Experiences

Young individuals form inflation expectations more strongly than older individuals, due to recent experiences accounting for a greater share of their lifetime history.

A POSITIVE THEORY OF INFLATION AND INFLATION VARIANCE

Inflation and inflation variance are positively associated, but there is no direct causal link between the average rate of inflation and either inflation variance or real output instability.

The Politics of Inflation

Inflation's causes are influenced by political, social, and economic factors, and addressing these interactions can help stop inflation.
